Laser Cleaning Machine
+ What models of laser cleaning machines do you have and what are the differences?

Laser cleaning machines are divided into pulse type and continuous type. At present, the pulse type has 100W 200W 300W 500W, and the continuous type has 1000W, 1500W, 2000W, 3000W.
With high precision, it is necessary to strictly control the heating of the substrate, and the application scenarios that require the substrate to be non-destructive, such as molds, should choose a pulsed type. For some large steel structures, pipes, etc., due to the large volume and fast heat dissipation, the requirements for damage to the substrate are not high, and continuous lasers is more suitable.

+ Working Efficiency of Laser Cleaning Machine

1000W: 1.28㎡/h, 1500W: 2.75㎡/h, 2000W: 9㎡/h, due to the different attachment conditions, the efficiency difference is relatively large and can reach 15-45㎡/h.
The roughness of the painted surface of stainless steel with continuous laser cleaner is Ra0.638-2.433, and the roughness of the surface of tungsten steel with pulse laser cleaning machine is Ra1.984-2.678.

+ Laser Cleaning Machine Lifespan and Consumables

The expected service life is about the length of the laser, usually 5-8 years.
Consumables: Protective lens and regularly replace the pure water, add antifreeze in winter. As long as it is properly operated and cleaned, the protective lens will not be easily damaged.

+ Can Laser Cleaning Machine Remove Scratches or Marks on the Surface of the Workpiece?

No, Laser cleaning machine is mainly to remove oxides or attachments on the surface of the workpiece, and the damage to the surface of the workpiece cannot be cleaned.

+ Can Laser Cleaning Machine Remove Particulates from Welds?

No, but it can remove the traces of blackening due to welding around the welding seam, which is conducive to subsequent painting.

+ Does the Laser Cleaning Machine Damage the Substrate?

There will be no damage to the substrate. The laser absorbs energy very well on rust and painted surfaces, so you may see the rust catch on fire. However, after the rust is cleaned, the substrate does not absorb the laser light enough, and there is no fire phenomenon, so the surface of the substrate will not be damaged.

+ Can the Laser Cleaning Machine Clean Non-planar Equipment such as Pipes?

Compared with traditional sandblasting and shot blasting cleaning, the advantage of laser cleaning is that the laser beam is a curved surface, which can well fit to pipes. Through remote infrared focusing, the edges and corners can be cleaned. Where the laser goes, all can be cleaned.

+ Will the Material become Hot after Cleaning?

There will be a rise in temperature, because the principle of the laser cleaning machine is that the laser ablates the oxidized substances attached to the surface of the infrastructure, and the temperature of the infrastructure will rise. However, compared with the pulse type and the continuous type, the continuous type laser cleaning machine has a higher temperature rise, but it is generally suitable for large substrates, and the heat dissipation is also fast.

+ Is the Laser Cleaning Machine Fiber Shape only Linear?

The continuous type has only a straight line, and the length of the straight line can be adjusted (10~160±10mm);
Pulsed laser cleaning machine can have linear, rectangular, circular, sine, text, spiral, Lissajous, and seven patterns can be adjusted.

+ What is the Warranty of the Laser Cleaning Machine?

1 Year Warranty for the Whole Machine, 2 Years Warranty for the Laser Source. (Consumables are not covered by warranty)

+ What is the Recommended Max Runtime of the Laser Cleaning Machine? 

When the machine is in normal condition, it is no problem to use it continuously for 8-12 hours a day. It has been tested for 7*24 hours and there is no abnormality.

+ Which software does sfx fiber laser engraver use and which operative system do I need to use?

SFX fiber laser engraver uses EZCAD2(lightburn compatible) and EZCAD3 software and can operate in any Windows system. It is easy to use. User manual and video in English with all the information for use the software, customer and technical support and remote assistance available.

+ What's the difference between fiber laser and MOPA laser engraving machines?

These two machines have a very similar or same outlook, inside, they work differently. The fiber laser machines use a technology called Q-switched that allows the power supplier to generate the path light only between 1 to 600 kHz. On the other hand, the Master Oscillator Power Amplifier most know as MOPA generate the power source with a different method, and this allows the machine has a pulse frequency with more amplitude than the fiber, from 1 to 4000 kHz. These enable the MOPA laser to have different engraving results over some plastics and metal materials in comparison of the Q-switched or fiber laser technology.
MOPA laser can do color marking on stainless steel, and black marking on alumimum, while ordinary fiber laser can not.

+ What can I engrave with a UV laser machine?

Mark: some metals, all glass, paper, fruits, wood, ceramic, garments
Mark and engrave: all plastics, some stones, leather

+ What can I engrave or cut with a CO2 galvo laser?

CO2 galvo laser can cut or engrave non-metal materials like wood, fruits, garments, leather, some plastics and others. The power for cut materials is little but it can engrave clear and fast materials as, paper, garments and light plastics.
